Abstract: In a method for operating a conditional access system for broadcast applications, the conditional access system comprising a number of subscribe rs and each subscriber having a terminal including a conditional access module and a secure device for storing entitlements, a source signal is encrypted using a first key (CW). The encrypted source signal is broadcasted for recei pt by the terminals, wherein entitlement control messages (ECM's) are sent to t he secure devices, the ECM's comprising the first keys (CW) encrypted using a service key (PT). Entitlement management messages (EMM's) are sent to the secure devices providing the service key (PT) required to decrypt encrypted first keys (CW). A cracked secure device which is used in an unauthorised manner is traced by sending different keys required to obtain the first keys  to different terminals or groups of terminals and monitoring the key information provided by a pirate. To this end search EMM's are sent to at least a part of the terminals, the search EMM's providing at least the servi ce key (PT) and a dummy key (PD1 or PD2). At least the search EMM's comprise identifiers identifying the keys (PT and PD1 or PD2), wherein first search EMM's with the keys (PT and PD1) are sent to a first part of the terminals a nd second search EMM's with thekeys (PT and PD2) are sent to a second part of the terminals An ECM identifying the service key (PT) to be used to decrypt the encrypted first key (CW), is sent to all secure devices just before the first key (CW) is needed to decrypt the source signal.

Title: Flossing device with advancing and tensioning mechanism
Inventor: BERGMAN MARK C
IPC: A61C15/04
Filed: 2002-03-15
Abstract: A hand-held dental flossing device has a housing with a handle that may be held with one hand. A dental floss supply is located in the housing and a winding gear is rotatably mounted to the housing. A free end of the dental floss strand from the floss supply is threaded through the housing into a floss exit arm of the housing where it passes through an exit opening to an exposed area of the flossing arm. Used dental floss returns into the housing, via a receiving opening, where it passes through an optional disinfectant supply before or as it wound onto the winding gear. The housing has an opening where the winding gear extends therefrom and is accessible to the forgers of the user's hand. The winding gear has teeth that cooperate with a stopper to form a one-way ratchet gear. A floss-tensioning button is located in the housing and has first and second ends extending from the housing. The first and second ends are accessible to the user's hand holding the handle of the flossing device. When in a first position, the tensioning button allows the floss strand to be readily advanced by winding the gear while in a second position, the floss strand is relatively taut so that winding the gear will even further tension the strand. The device may have an F-shaped cross-section, enlarged, funnel-shaped openings for the floss to exit and enter the housing, and a disinfectant supply for disinfecting used floss. The device may be reloadable with floss.

Title: Methods for efficient early protocol detection
Inventor: ABROL NISCHAL
IPC: H04L12/56
Filed: 2000-09-07
Abstract: A method and system that detects protocol and configuration messages in a PPP  packet without having to unframe the entire packet. The method includes a communication device (MT2) that receives a plurality data frames (S306), wherein the communication device is capable of ascertaining the beginning of an information portion (S305) within the received frames.
